METHODS AND COMPOSITIONS FOR TREATING AND PREVENTING URINARY TRACT INFECTIONS
BACKGROUND
[0001] Urinary tract infections (UTIs) are among the most common infectious diseases, and account for considerable healthcare outlays for society. Microorganisms can reach the urinary tract by a hematogenous or a lymphatic route, but most clinical and experimental evidence shows that ascension of the urethra by microorganisms constitutes the most common route leading to urinary tract infection, in particular by enteric organisms (Escherichia coli and other enterobacteria). Women are at greater risk of developing a UTI than are men.
[0002] Lower urinary tract symptoms (LUTS) become increasingly bothersome as men age, with a prevalence of moderate-to- severe symptoms rising to nearly 50% of men in their eighties. The term LUTS cover both gender but is more often applied to men. LUTS may or may not be related to benign prostatic hyperplasia (BPH), a histological condition characterized by the non- malignant overgrowth of prostatic tissue surrounding the urethra that occurs in 50% of men in their fifties and 90% of men in their eighties. LUTS can also arise from age-related bladder detrusor dysfunction and other sympathetic conditions. LUTS are further classified as voiding or storage symptoms and defined by the international prostate symptoms score (IPSS), a validated tool, widely used among the medical and scientific community.
[0003] Voiding symptoms include urinary hesitancy, delay in initiating micturition, intermittency, involuntary interruption of voiding, weak urinary stream, straining to void, a sensation of incomplete emptying, terminal dribbling, and may be caused by prostate enlargement or tissue inflammation. Storage symptoms can include urinary frequency, nocturia, urgency, incontinence and bladder pain or dysuria, and may be caused by bladder detrusor overactivity. Overactive bladder (OAB) is a condition more related with women where there is a frequent feeling of needing to urinate to a degree that it negatively affects a person's life.
[0004] Although LUTS and LUTS due to BPH are not a life-threatening condition, the impact of LUTS on quality-of-life (QoL) can be significant and treatment is necessary in most cases to avoid complications. Risk factors include age, prostatic volume and peak urinary flow rate as well as lifestyle, dietary pattern, alcohol consumption, physical activity or genetic factors. Upon diagnosis, watchful waiting is recommended in approximately 34% of cases in the United States. Registered pharmacological treatments for UTI, LUTS and OAB may be responsible for a variety of side effects, thus necessitating development of new treatments. SUMMARY

[0090] Such pharmaceutical excipients can be liquids, such as water and oils, including those of petroleum, animal, vegetable, or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical excipients can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea and the like. In addition, auxiliary, stabilizing, thickening, lubricating, and coloring agents can be used. In one embodiment, the pharmaceutically acceptable excipients are sterile when administered to a subject. Suitable pharmaceutical excipients also include starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene glycol, water, ethanol and the like. The present therapeutic compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents. In one embodiment, the composition is in the form of a capsule (see, e.g., U.S. Patent No. 5,698,155). Other examples of suitable pharmaceutical excipients are described in Remington's Pharmaceutical Sciences 1447-1676 (Alfonso R. Gennaro eds., 19th ed. 1995).
[0091] In some embodiments, a composition described herein is formulated in accordance with routine procedures as a composition adapted for oral administration to human beings (sch as a pharmaceutical composition or a nutraceutical composition). Compositions for oral delivery can be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, softgels, syrups, or elixirs for example. Orally administered compositions can contain one or more agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents such as peppermint, oil of wintergreen, or cherry; coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions can be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active therapeutic composition is also suitable for orally administered compositions. In these latter platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time delay material such as glycerol monostearate or glycerol stearate can also be useful. Oral compositions can include standard excipients such as mannitol, lactose, starch, maltodextrin, cyclodextrins, alginate, arabic or guar gum, magnesium stearate, sodium saccharin, cellulose, and magnesium carbonate. In one embodiment, the excipients are of pharmaceutical grade.
[0092] Pharmaceutical dosage forms for oral use can be obtained through combination of a therapeutic composition described herein with a solid excipient, optionally grinding a resulting mixture, and processing the mixture of granules, after adding suitable additional compounds, if desired, to obtain tablets or dragee cores. Suitable solid excipients in addition to those previously mentioned are carbohydrate or protein fillers that include, but are not limited to, sugars, including lactose, sucrose, mannitol, or sorbitol; starch from com, wheat, rice, potato, or other plants; cellulose such as methyl cellulose, hydroxypropylmethyl-cellulose or sodium carboxymethylcellulose; and gums including arabic and tragacanth; as well as proteins such as gelatin and collagen. Maltodextrin and cyclodextrins can also be used. If desired, disintegrating or solubilizing agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, alginic acid, or a salt thereof, such as sodium alginate.
[0093] Capsules for oral use include hard gelatin capsules in which the active ingredient is mixed with a solid diluent, and soft gelatin capsules wherein the active ingredients is mixed with water or an oil such as peanut oil, liquid paraffin or olive oil.
[0094] Softgels for oral use may consist of a gelatin based shell surrounding a liquid fill. Softgel shells can be made of a combination of gelatin, water, opacifier and a plasticiser such as glycerin and/or sorbitol.
[0095] Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses. Therapeutic compositions described herein can be administered by controlled-release or sustained release means or by delivery devices that are well known to those of ordinary skill in the art. Examples include, but are not limited to, those described in U.S. Patent Nos. 5,674,533; 5,059,595; 5,120,548; 5,073,543; 5,639,476 and 5,354,556, each of which is incorporated herein by reference in its entirety. Such dosage forms can be useful for providing controlled or sustained release of one or more active ingredients using, for example, hydropropylmethyl cellulose, other polymer matrices, gels, permeable membranes, osmotic systems, multilayer coatings, microparticles, liposomes, microspheres, or a combination thereof to provide the desired release profile in varying proportions. Suitable controlled or sustained release formulations known to those skilled in the art, including those described herein, can be readily selected for use with the active ingredients of the invention. The present disclosure thus encompasses single unit dosage forms suitable for oral administration such as, but not limited to, tablets, capsules, gelcaps, and caplets that are adapted for controlled or sustained release.
[0096] In some embodiments, a controlled or sustained release composition comprises a minimal amount of a therapeutic composition to alleviate the symptoms of, treat or prevent lower urinary tract symptoms (LUTS), urinary tract infections(UTIs), pelvic organ prolapse (POP), urolithiasis or hyperoxaluria, benign prostatic hyperplasia (BPH), erectile dysfunction (ED), urinary incontinence, bladder obstruction, interstitial cystitis, overactive bladder (OAB), underactive bladder, prostatitis, bladder and prostate inflammation, prostate fibrosis or pelvic pain in a patient over a period of time. Advantages of controlled or sustained release compositions include extended activity of the drug, reduced dosage frequency, and increased subject compliance. In addition, controlled or sustained release compositions can favorably affect the time of onset of action or other characteristics, such as blood levels active ingredients present in the therapeutic composition, and can thus reduce the occurrence of adverse side effects.
[0097] Controlled or sustained release compositions can initially release an amount of an active ingredient present in the therapeutic composition that promptly produces the desired therapeutic or prophylactic effect, and gradually and continually release other amounts of the active ingredients present in the therapeutic composition to maintain this level of therapeutic or prophylactic effect over an extended period of time. To maintain a constant level of an active ingredient present in the therapeutic composition in the body, active ingredients present in the therapeutic composition thereof can be released from the dosage form at a rate that will replace the amount of the active ingredients present in the therapeutic composition being metabolized and excreted from the body. Controlled or sustained release of an active ingredient can be stimulated by various conditions, including but not limited to, changes in pH, changes in temperature, concentration or availability of enzymes, concentration or availability of water, or other physiological conditions or compounds.
[0098] The amount of the composition of the present disclosure (comprising a cranberry component and a saponin), the pharmaceutical composition or the nutraceutical composition that is useful for treating any of the diseases and symptoms described before (such as LUTS, OAB, etc) can be determined by standard clinical techniques. In addition, in vitro or in vivo assays can optionally be employed to help identify optimal dosage ranges. The precise dose to be employed can also depend on the route of administration, and the seriousness of the condition being treated and can be decided according to the judgment of the practitioner and each subject's circumstances in view of, e.g., published clinical studies. Suitable effective dosage amounts, however, range from about 1 mg to about 5 grams about every 24 hours, although they are typically about 500 mg or less per every 24 hours. In one embodiment, the effective dosage is about 50 mg, about 100 mg, about 150 mg, about 200 mg, about 250 mg, about 300 mg, about 350 mg about 400 mg, about 450 mg about 500 mg, about 600 mg, about 700 mg, about 800 mg, about 900 mg, about 1 g, about 1.2 g, about 1.4 g, about 1.6 g, about 1.8 g, about 2.0 g, about 2.2 g, about 2.4 g, about 2.6 g, about 2.8 g, about 3.0 g, about 3.2 g, about 3.4 g, about 3.6 g, about 3.8 g, about 4.0 g, about 4.2 g, about 4.4 g, about 4.6 g, about 4.8 g, and about 5.0 g, every 24 hours. Equivalent dosages can be administered over various time periods including, but not limited to about every 2 hours, about every 4 hours, about every 6 hours, about every 8 hours, about every 24 hours, about every 36 hours, about every 48 hours, about every 72 hours, about every week, about every two weeks, about every three weeks, about every month, and about every two months. The effective dosage amounts described herein refer to total amounts administered; that is, if more than one therapeutic composition is administered, the effective dosage amounts correspond to the total amount administered.
[0099] The compositions described herein can be administered as long as the symptoms persist or longer. In some embodiments, the therapeutic composition is administered for 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 days.
[0100] The dosage regimen utilizing the therapeutic or nutraceutical compositions described herein can be selected in accordance with a variety of factors including type, species, age, weight, sex and medical condition of the subject; the severity of the condition to be treated; the route of administration; and the renal or hepatic function of the subject.
[0101] A therapeutic or nutraceutical composition described herein can be administered in a single daily dose, or the total daily dosage can be administered in divided doses of two, three or four times daily.
[0102] The compositions described herein can be assayed in vitro or in vivo for the desired therapeutic or prophylactic activity prior to use in humans. Animal model systems can be used to demonstrate safety and efficacy.
[0103] As used herein, the recitation of a numerical range for a variable is intended to convey that the invention may be practiced with the variable equal to any of the values within that range. Thus, for a variable which is inherently discrete, the variable can be equal to any integer value within the numerical range, including the end-points of the range. Similarly, for a variable which is inherently continuous, the variable can be equal to any real value within the numerical range, including the end-points of the range. As an example, and without limitation, a variable which is described as having values between 0 and 2 can take the values 0, 1 or 2 if the variable is inherently discrete, and can take the values 0.0, 0.1, 0.01, 0.001, or any other real values > 0 and < 2 if the variable is inherently continuous.
[0104] As used herein, the term “treatment” or grammatical equivalents encompasses the improvement and/or reversal of the symptoms of disease (e.g. LUTS). The term “treatment” refers to both therapeutic treatment and prophylactic or preventative measures. For example, those who may benefit from treatment with compositions, uses and methods of the present invention include those already with a disease and/or disorder (e.g., elevated cholesterol levels) as well as those in which a disease and/or disorder is to be prevented (e.g., using a prophylactic treatment of the present invention). [0105] The term “prevention” in relation to a given disease or disorder means: preventing the onset of disease development if none had occurred, preventing the disease or disorder from occurring in a subject that may be at risk or predisposed to the disorder or disease but has not yet been diagnosed as having the disorder or disease, and/or preventing further disease/disorder development if already present.
[0106] As used herein, the term “at risk for disease” refers to a subject (e.g., a human) that is predisposed to experiencing a particular disease. This predisposition may be genetic (e.g., a particular genetic tendency to experience the disease, such as heritable disorders), or due to other factors (e.g., age, weight, environmental conditions, exposures to detrimental compounds present in the environment, etc.). Thus, it is not intended that the present invention be limited to any particular risk, nor is it intended that the present invention be limited to any particular disease.
[0107] A therapeutically effective amount of any embodiment of the present invention is determined using methods known to pharmacologists and clinicians having ordinary skill in the art. For example, an effective amount can be determined subjectively by administering increasing amounts of the compositions of the present invention until such time the patient being treated shows reduction in LUTS symptoms for example using the Urinary Tract Infection Symptoms Assessment Questionnaire (UTISA) as described in the experiments of the present invention,
[0108] As used herein, unless specifically indicated otherwise, the word "or" is used in the inclusive sense of "and/or" and not the exclusive sense of "either/or."
[0109] As used herein, "about" means within ±10%. For example, "about 1" means "0.9 to 1.1", "about 2%" means "1.8% to 2.2%", "about 2% to 3%" means "1.8% to 3.3%", and "about 3% to about 4%" means "2.7% to 4.4%. "
[0110] The patent and scientific literature referred to herein establishes knowledge that is available to those of skill in the art. The issued U.S. patents, allowed applications, published foreign applications, and references that are cited herein are hereby incorporated by reference to the same extent as if each was specifically and individually indicated to be incorporated by reference.
[0111] While a number of embodiments of the invention have been described, it is apparent that the basic examples may be altered to provide other embodiments that utilize the compositions, methods, and processes of this invention. Therefore, it will be appreciated that the scope of this invention is to be defined by the appended claims rather than by the specific embodiments that have been represented by way of example herein.

[0124] 2.5 Strategies for Recruitment and Retention Subjects are recruited for the study from St. Joseph’s Hospital in London, ON.
Subjects are recruited based on the Inclusion and Exclusion criteria listed in Section 2.2 and 2.3, respectively.
[0125] 3. Study Procedures
Subjects have two in-office visits. At Visit 1, the subjects are required to provide a urine sample to test for leukocyte or nitrites, perform a urine culture and a pregnancy test. Subjects are also asked to provide a stool sample if possible. Recognizing that providing a stool sample at Visit 1 may not be possible, the subject take a stool sample at home and identify this as Day 1. After taking the stool sample the subjects begin taking the product substance immediately and then again that evening even if the first dose is taken in the afternoon and not the morning. The subjects shall then take the remaining product in the morning and evening as instructed until all 28 doses are gone and collect urine each day for 14 days and a second stool sample on Day 14 before returning for Visit 2.
[0126] 3.1. Sample Collection and Shipping to Laboratory for Analysis
[0127] Urine sample collection
[0128] Urine sample are collected at Visits 1, every day after Visit 1, and at Visit 2. Urine will be collected using Peezy and AssayAssureTM urine collection kits. Each subject is asked to wash their hands with soap and water and collect midstream urine.
[0129] Peezy midstream urine collection device (Forte Medical, London, UK) allows the collection of approximately 30 mL of urine into a sterile container. It has been reported to allow the collection of urine that is significantly less contaminated with bacteria that was distinct from the periurethra compared to the standard clean catch method.
[0130] AssayAssureTM (Sierra Molecular Corp, Princeton, NJ) is a urine sample stabilization system designed to preserve cell viability by slowing cellular metabolism and providing thermal protection for up to 26 days at room temperature. After subjects collect urine using Peezy collection device, the urine is transferred and stored in the AssayAssure transport tubes. The tubes are stored at a refrigerated temperature (2-4’C) and brought into clinic at Visit 2. The priority for the urine specimen on Visit 1 is clinical UTI testing (UA and reflex urine culture). All remaining urine from Visit 1 are saved for microbiome research purposes (sequencing of microbiome). A minimum sample quantity of 20 mL is need for the microbiome testing.
[0131] 4. Study Intervention
[0132] 4.1 Study Intervention Following baseline assessment, subjects are provided with study product, and instructed to take one 450 mg cranberry capsule, and one 50 mg quillaja capsule in the morning and to repeat the same dose in the evening (Schema 1). The total daily dosage of cranberry will be 900 mg, and the total dosage of quillaja will be 100 mg per day. If UTI symptoms persist before Visit 2, subjects can start nitrofurantoin lOOmg PO BID for 5 days that is provided at Visit 1 at any time.
[0133] 4.2 Dosing and Administration
Subjects are instructed to take one 450 mg cranberry capsule, and one 50 mg quillaja capsule in the morning and another in the evening. The total daily dosing will be 900 mg of cranberry, and 100 mg of quillaja per day for 14 days. If a subject is starting in the afternoon, they should take the morning dose at that time and then later take the evening dose. If subjects accidentally skip a dose they can double up on the next dose only if taken on the same day.
[0134] 4.3 Duration of Therapy and Criteria for Removal from Study
[0135] Subjects take cranberry 900mg and quillaja lOOmg daily for 14 days until one of the following criteria applies:
• Disease progression,
• Intercurrent illness that prevents further administration of treatment,
• Unacceptable adverse event(s),
• Subject decides to withdraw from the study, or
• General or specific changes in the subject’s condition render the subject unacceptable for further treatment in the judgment of the investigator.
[0136] 5. Measurement of Effect
The results of this study are contingent upon subjects’ responses to the UTISA questionnaire tables 1 and 2 ( Clayson D, Wild D, Doll H, Keating K, Gondek K. Validation of a patient- administered questionnaire to measure the severity and bothersomeness of lower urinary tract symptoms in uncomplicated urinary tract infection (UTI): the UTI Symptom Assessment questionnaire. BJU Int. 2005 Aug;96(3):350-9 ) and study forms, which provide the efficacy of cranberry and quillaja in alleviating UTI symptoms. These measurements are to be completed by the subjects throughout the study.
[0137] Primary endpoint measures: The degree of symptoms of UTI is measured based on subject responses recorded on UTISA. Time to UTI antibiotic initiation is assessed using study forms.
Secondary endpoint measure:
Urinary and gut microbiome factors such as the magnitude of initial dysbiosis, changes prior to antibiotic initiation will be measured.

Table 2. UTISA questionnaire for use at Day 2-14 (0138) 6. Statistical Considerations.
The Statistical Package for the Social Sciences (SPSS, Chicago, IL) is used to perform all statistical analyses. Statistical significance is set at P < 0.05 a priori. Descriptive analyses are used to describe the characteristics of the patient sample (mean, standard deviation, percentages, and frequencies). One-way analysis of variance is used to evaluate the continuous variables, and chi-square tests is used to evaluate the categorical variables.
(0139) Power Calculation and Sample Size.
The probability is 80 percent that the study will detect a treatment difference at a two-sided 0.05 significance level, if the true difference pre and post treatment is a reduction of 7.5
symptom units on the UTISA questionnaire. This is based on the assumption that the standard deviation of the response variable is 4.6.
[0140] 7. Analysis of Endpoints
[0141] 7.1 Analysis of Primary Endpoints
Primary end point 1) Time to symptom resolution measured by the subject responses on UTISA Statistical analysis.
Primary end point 2) Time to UTI antibiotic initiation is assessed using study forms. Subjects have access to a clinically prescribed UTI antibiotic. Subjects are asked to record each day their intake of any antibiotic during the study period. The nonuse of the rescue antibiotic is considered a successful response.
[0142] 8. Microbial composition data for Urobiome study
[0143] 8.1 Methods:
Urine samples were processed within 6 hours of their collection as previously described (A1 and Burton, 2021). Fecal samples were collected on toilet paper and processed as previously described (A1 et al., 2018). Microbiota sequencing was performed on an Illumina MiSeq as previously described following PCR amplification of the V4 region of the 16S rRNA gene (Al et al., 2020). Raw reads were demultiplexed using Cutadapt (v3.4)(Martin, 2011) and quality filtered following the DADA2 pipeline (Callahan et al., 2016). The remaining filtered reads were assigned taxonomy to amplicon sequence variants (SVs) using the SILVA (vl38) training set (Quast et al., 2013). Downstream analysis was performed with ALDEx2, Vegan, and core R packages (Fernandes et al., 2013; Oksanen et al., 2019; R Core team, 2019).
[0144] 8.2 Results:
The microbiota was characterized for 13 samples from one participant, of which three were fecal and ten were urine per person. The raw reads were stringently filtered for quality: of the initial average yield of 131 729 reads per sample, filtering pruned an average of 13%, such that approximately 117 000 reads per sample were maintained for the downstream analyses. 2541 SVs were initially identified in the samples; a further filtering was performed such that SVs were removed that did not comprise >1% of the relative abundance in any sample, and did not assign to chloroplast, mitochondrial, or eukaryotic DNA. 116 SVs remained and were utilized for downstream analyses.
[0145] When evaluating the microbiota, the fecal microbiota was not significantly altered during the 14 days, as measured by Shannon’s index of alpha diversity or Aitchison distance from the baseline (data not shown). In contrast, although not statistically significant, the relative abundance of the genus Escherichia in urine samples appears to decrease by day 14 in comparison to the baseline values on day 1 (Figures la/b & 2a/b).
[0146] Figures la and lb show the relative bacterial abundance of all samples. Each vertical bar represents the relative SV abundance within a single sample. Samples are grouped by participant and sample type. Relative abundance of SVs is coloured by genera, with the 20 most abundant genera shown in the legend. Samples are coloured by sample type (fecal samples are gray, urine samples are yellow), and denoted with the day of sample collection. Figure la is in color, Figure lb in grayscale, but they show the same data. [0147] Figures 2a and 2b show the relative bacterial abundance from baseline, midpoint, and day 14. Each vertical bar represents the relative SV abundance within a single sample. Samples are grouped by participant and sample type. Relative abundance of SVs is coloured by genera, with the 20 most abundant genera shown in the legend. Samples are coloured by sample type (fecal samples are gray, urine samples are yellow), and denoted with the day of sample collection. Figure 2a is in color, Figure 2b in grayscale, but they show the same data.
[0148] Participant 1 urine samples were significantly higher in Shannon’s index of alpha diversity with higher variability over time (two-tailed student’s t-test, P = 0.021; F test of variances, P = 0.018), and trended towards higher Beta diversity as measured by Aitchison distance from baseline (two-tailed students t-test, P = 0.08 respectively). [0149] When evaluating the symptoms, using the UTISA questionnaire, participant 1 experienced a noticeable decrease in the severity and bothersome ratings of her symptoms at Day 14 (Table 3):
Table 3. Results of the UTISA questionnaire for participant 1
[0150] The decrease in Escherichia in urine and the increase in microbiome diversity appear concomitantly with the decrease of symptoms at Day 14.
